CUTTNG DEVICE EUR CTGARETTE MACHINES.

Application filed November 10, 1925, Serial No. 68,206, and FranceJanuary 8, 1925.

My invention has for its object a device for cuttingn ofi' thepaper-covered roll of tobacco which is discharged from cigarette machineoperating` on the continuous principle.

The said device comprises a l'cnife-carrying slide acting` according toa known principle in such manner that when the roll is to be cut, theslide will move parallel with the said roll and at the same speed as thelatter. The knives mounted upon the slide are given a rapid rotation.

The appended drawing shows by way of example an embodiment of thel saidinvention.

.E 1g. 1 is a lengthwise section. Fig'. 2 a side view and,

Fig. 3 a plan view.

The said device comprises a driving shaft to which is keyed a pinion 2which drivesthrough an intermediate wheel 3-a pinion l mounted on theshaft 5. 'Upon the latterl is mounted for instance by the pins 6 the arm7 carrying the removably secured knives 8.

r.The slide 9 is mounted at one end of the shaft 5 which is rotatable inthe bearing` 10 disposed on said slide but is secured to the latter inthe lengthwise direction by the4 nut 11. The other end of the shaft 5 isslidable in a ring- 12 which is secured to the pinion 1i, but .it can beactuated by the said pinion by means of a key 13 engaged in a slot 11i.

The slide 9 is secured to the rods 15, slidable in the supports 16,whereby the slide will be suitably guided. rllhe shaft 1 carries a bevelgear 17 coacting` with a like gear 1S keyed to the vertical shaft 19.Said sh aft is provided with a disk 2O upon which is pivoted by thecrank pin 21 a link 22 whose other end is pivoted to the slide 9, thusproviding` for the reciprocating motion of the slide.

The said crank pin is preferably engaged in a `guide slot in the disk20, and it can be held at any point therein, so as to regulate thestroke of the slide. By this means I am enabled to adjust the stroke ofthe carriage according` to the length of the cigarettes to be cut off,so that the speed of the slide durina the cutting operation shall alwaysbe exactly the same as the speed of the roll of tobacco to be cut.

The slide 9 carries the guides 23 which are continuously traversed bythe cigarette roll 24 and which laterally maintain the knife blades 8.

Obviously, instead of two blades, I may employ a single blade or anyother suitable number such as three, four or the like, withoutdeparting` from the principle of the invention` The said device may beprovided with all desired accessory means, and chiefly with means forsharpening` the said blades during the operation of the apparatus.

Havingthus described my apparatus, what I claim as new therein, and myown invention, is:-

In a device for cutting` off the. cigarette roll which is discharged ata given speed from a cigarette machine, the combination of a slidehaving` a reciprocating motion, the said motion being parallel with themotion of the cigarette roll and its speed beine; equal to that of thesaid roll, the said slide containing` at least one rapidly rotatingknife,` a rotatable shaft mounted on the said slide and adapted tofollow the reciprocating motion of the slide, a driving sleeve in whichthe said shaft is disposed, means connecting the shaft with the saidsleeve whereby the shaft may slide within the sleeve and may also berotated by the latter, a support whereon the said sleeve is mounted andwhich prevents the lengthwise sliding of the said sleeve, a rotatabledrivingshaft, and means for driving the said sleeve from said drivinglshaft.

In testimony whereof have hereunto aflixed my signature.

ETIENNE DANGER.
